bool FlowGeometry::getInterpolationAt	(	CoreVector3	pos,
		int *	vtxID,
		float *	coef
	)

Returns true if inside. Stores the vertex indices and interpolation weights for the given position in the arrays.

Stores the indexes and weights of vertices surrounding the given position. This information can be used later on for interpolation of channel values.

Parameter:

	pos	geometrical position for the lookup
	vtxID	list of surrounding vertices (given by vertex ID)
	coef	list of surrounding vertex weights (sum == 1.0)

Rückgabe:

true if the given position is inside of the geometrical boundaries
